Hi, I'm having some major difficulties with WILD:

My room is completely dark en there are no sounds, so that problem is fixed, but then, when I try to WILD, I can get very relaxed, flashing lights come quite fast and I can also feel the tingling sensations and that's where it ends... everytime I start tingling, I "wake" up... Or maybe I'm doing it wrong? I let my mind drift, just like when you're really dreaming and really 'seeing' everything you think about, or is that wrong? because if I'm not supposed to do that, then I never get any further than flashing lights... hard hard hard! I've tried many times though.
Then, second problem: if it takes too long evrything starts to ache, I just have to move, I can't stay in the same position very long, just like when I go to sleep normally: I move a lot.
Anyone got any ideas?
